Organised Randoms: Learning and correcting for systematic galaxy clustering patterns in KiDS using self-organising maps
Harry Johnston, Angus H. Wright, Benjamin Joachimi +10
We present a new method for the mitigation of observational systematic effects in angular galaxy clustering via corrective random galaxy catalogues. Real and synthetic galaxy data,…
Strong detection of the CMB lensingxgalaxy weak lensingcross-correlation from ACT-DR4,PlanckLegacy and KiDS-1000
Naomi Clare Robertson, David Alonso, Joachim Harnois-Déraps +48
We measure the cross-correlation between galaxy weak lensing data from the Kilo Degree Survey (KiDS-1000, DR4) and cosmic microwave background (CMB) lensing data from the Atacama C…
KiDS-1000 Cosmology: constraints beyond flat CDM
Tilman Tröster, Marika Asgari, Chris Blake +26
We present constraints on extensions to the flat CDM cosmological model by varying the spatial curvature , the sum of the neutrino masses , the dark energy equati…
Photometric selection and redshifts for quasars in the Kilo-Degree Survey Data Release 4
S. J. Nakoneczny, M. Bilicki, A. Pollo +10
We present a catalog of quasars and corresponding redshifts in the Kilo-Degree Survey (KiDS) Data Release 4. We trained machine learning (ML) models, using optical ugri and near-in…
KiDS-1000 catalogue: Redshift distributions and their calibration
H. Hildebrandt, J. L. van den Busch, A. H. Wright +15
We present redshift distribution estimates of galaxies selected from the fourth data release of the Kilo-Degree Survey over an area of deg (KiDS-1000). These redshif…
KiDS-1000 Cosmology: Cosmic shear constraints and comparison between two point statistics
Marika Asgari, Chieh-An Lin, Benjamin Joachimi +22
We present cosmological constraints from a cosmic shear analysis of the fourth data release of the Kilo-Degree Survey (KiDS-1000), doubling the survey area with nine-band optical a…
KiDS-1000 Cosmology: Multi-probe weak gravitational lensing and spectroscopic galaxy clustering constraints
Catherine Heymans, Tilman Tröster, Marika Asgari +31
We present a joint cosmological analysis of weak gravitational lensing observations from the Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from…
KiDS-1000 catalogue: Weak gravitational lensing shear measurements
Benjamin Giblin, Catherine Heymans, Marika Asgari +19
We present weak lensing shear catalogues from the fourth data release of the Kilo-Degree Survey, KiDS-1000, spanning 1006 square degrees of deep and high-resolution imaging. Our `g…
KiDS-1000 Methodology: Modelling and inference for joint weak gravitational lensing and spectroscopic galaxy clustering analysis
B. Joachimi, C. -A. Lin, M. Asgari +24
We present the methodology for a joint cosmological analysis of weak gravitational lensing from the fourth data release of the ESO Kilo-Degree Survey (KiDS-1000) and galaxy cluster…
KiDS+GAMA: The weak lensing calibrated stellar-to-halo mass relation of central and satellite galaxies
Andrej Dvornik, Henk Hoekstra, Konrad Kuijken +13
We simultaneously present constraints on the stellar-to-halo mass relation for central and satellite galaxies through a weak lensing analysis of spectroscopically classified galaxi…
GAMA+KiDS: Empirical correlations between halo mass and other galaxy properties near the knee of the stellar-to-halo mass relation
Edward N. Taylor, Michelle E. Cluver, Alan Duffy +16
We use KiDS weak lensing data to measure variations in mean halo mass as a function of several key galaxy properties (namely: stellar colour, specific star formation rate, Sersic i…
Testing gravity using galaxy-galaxy lensing and clustering amplitudes in KiDS-1000, BOSS and 2dFLenS
Chris Blake, Alexandra Amon, Marika Asgari +18
The physics of gravity on cosmological scales affects both the rate of assembly of large-scale structure, and the gravitational lensing of background light through this cosmic web.…
Minimising the impact of scale-dependent galaxy bias on the joint cosmological analysis of large scale structures
Marika Asgari, Indiarose Friswell, Mijin Yoon +5
We present a mitigation strategy to reduce the impact of non-linear galaxy bias on the joint `pt' cosmological analysis of weak lensing and galaxy surveys. The -sta…
